Notes:
Airtightness testing is mandatory — Take 3 sealed shell spaces, pressurize them on the testing machine, maintain a pressure of ≥1 MPa for 1 minute; qualification is determined by no gas leakage from the four sealing walls. For each shift, randomly select one cell for disassembly inspection to confirm that the cover plate deformation is ≤0.3 mm.
